AYUDENME A RESOLVER ESTAS ECUACIONES
1-. x – 7 = 6
2-. x – 11 = – 3 + 5
3-. 3x + 18 = – 3
4-. 3x + 1 = – 2x + 6

Answer 1

1)

$x - 7 = 6 \\ x = 6 + 7 \\ x = 13$

2)

$x - 11 = - 3 + 5 \\ x = - 3 + 5 + 11 \\ x = 13$

3)

$3x + 18 = - 3 \\ 3x = - 3 - 18 \\ 3x = - 21 \\ x = - 21 \div 3 \\ x = - 7$

4)

$3x + 1 = - 2x + 6 \\ 3x + 2x = 6 - 1 \\ 5x = 5 \\ x = 5 \div 5 \\ x = 1$
